[TowerTalk] N/C/BNC/TNC Connectors

[Alastair Beaton]

Hi,

I seem to recall a piece of trivia in an '80s QST that explained the
designation of connectors.

"N" and "C" connectors (remember them?) had as their letters the initial of
their designer's surname. I think that BNCs and TNCs were joint efforts
(Bayonet and Thread) between "Mr N" and "Mr C".

This sounds very twee and unlikely, but it's stuck in my mind.

Maybe some TowerTalkian can set the record straight.

BTW, I've noticed 7/16 EIA is being increasingly promoted as THE connector
for use with LMR-400/600 and Heliax. Prices are broadly similar to N-types.
Does anyone have comparative data and/or comments?
